This isn’t about graphics. It is about Jetson Orin Nano. The page
https://docs.nvidia.com/jetson/jetpack/install-jetpack/index.html
suggests these apt commands
sudo add-apt-repository --remove “deb https://repo.download.nvidia.com/jetson/common r35.3 main”
sudo add-apt-repository "deb https://repo.download.nvidia.com/jetson/common/orin-nano r35.3 main"
The second command fails with error: release does not have a release file. That is because Err:8 https://repo.download.nvidia.com/jetson/common/orin-nano r35.3 Release
404 Not Found [IP: 173.222.162.162 443]
In other words https://repo.download.nvidia.com/jetson/common/orin-nano r35.3 Release is not yet available. Can you please correct this problem?
